| 摘 要： | 以水槽试验为基础，对非淹没丁坝附近的水流现象进行了定性描述。采用三维声学多普勒流速仪对丁坝附近的水流特性进行了系统的试验研究，较为全面的分析了弯道内丁坝附近水流的三维时均流速和水面形态等，进一步表明绕丁坝近场流动的强三维非恒定性，为相关的工程实践提供理论依据。

| Abstract: | The flow patterns close to the non-submerged spur dikes are discussed on the basis of flume experiment. The paper presents an experimental study on the flow characteristics close to the spur dikes by means of the advanced three-dimensional acoustics Doppler current meter. Time-averaged velocity and water surface patterns are analyzed scientifically from all aspects. The observed information shows that the flow close to the spur dike is three dimensional and unsteady due to the fluctuating circulation zone and surface wave. So, the study provides reference for similar projects. |
